But, no, they do use chloroform in root canals. I asked about it when they were done (and looked it up later in the day because I was sure I couldn't have remembered him right. Now I'm wishing I hadn't looked that up, because I found a bunch of sites about the dangers of root canals and why you shouldn't have them. Things I won't be reading right now because what's done is done.
I'll be back in the sewing room later today, trying to distract myself from the temporary filling.
